Dan the Weatherman Posted September 15, 2015 Report Share Posted September 15, 2015 There is a low level cumulus deck here in Orange today, which is almost always a positive sign when there is rain in the forecast. This indicates that the lower levels of the atmosphere are moist as opposed to being dry. This once again came true. It rained substantially early this morning here in Orange, and filled at least one of my rain barrels and filled the 4 large pots that I have been setting out as of late to catch rainwater off the roof of my house. I will post a total later on when the rain ends. Quote Link to comment Share on other sites More sharing options...

It would be nice to get a couple of more tropical rain events like this before the Santa Anas begin to blow sometime next month. The San Diego and Oxnard NWS AFDs are mentioning the possibility of another intrusion of tropical moisture Tuesday or Wednesday of next week for Socal, so maybe if we are lucky, we will get something similar once again.

Mattywx101 Posted September 16, 2015 Report Share Posted September 16, 2015 Yesterday while driving up to Paso Robles, I could see a smoke-no smoke line up in the atmosphere, configured in a southwest to northeast orientation, moving from northwest to southeast across the area. That lined up with the coldfront passage. Now we have the best air quality seen around here in several weeks. Last night Low of 48 is the lowest minimum since July 1st. 2 Quote Link to comment Share on other sites More sharing options...

Dan the Weatherman Posted September 16, 2015 Report Share Posted September 16, 2015 1.33" fell here in Orange with yesterday's storm, which is very impressive for a September storm. This total would be respectable for a storm during the heart of winter, such as in January or February. Hopefully this is a sign of things to come this winter! I will post a total later on for the summer, as this has been the rainiest astronomical summer (June 20-21 to September 20) that I have ever seen here in Orange as far as I can remember back (early 1980's). I would estimate that I have probably received about 2.75" of rainfall during this period including the remnants of Delores back in July and a couple of other miscellaneous thunderstorm outbreaks in between.

Guest happ Posted September 16, 2015 Report Share Posted September 16, 2015 Lower elevations were cooler this morning but the real difference was dew point temp. The relative humidity yesterday was 100% locally. Tonight should be very cool before minimums warm up later this week. Dan, I can recall the El Nino summer of 1982-83 as wet also. That was the first time I experienced a "tropical wave" come ashore with excessive lightning, wind and brief heavy shower. Quote Link to comment Share on other sites More sharing options...

'Doctor George' was the popular met on Channel 7 and showed an arc of advancing clouds/ storm front on radar. By early afternoon lightening could be seen all over even under partly cloudy skies and the humidity was excessive. The storm only lasted maybe an hour but it dropped a lot of rain. The storm that reminded me of this tropical wave was Dolores in July; it was hot and extremely muggy that night; the rain felt uncommonly warm.

Guest happ Posted September 17, 2015 Report Share Posted September 17, 2015 This is very encouraging for additional moisture if it verifies: NWS_SDTHIS LOW AND THIS SOUTHWEST HIGH WILL PROPEL SOUTHERLY FLOW AND SEND TROPICAL MOISTURE INTO OUR REGION MONDAY THROUGH WEDNESDAY. IT WILL ALSO BRING BACK THE HEAT AND HUMIDITY WE ARE USED TO THIS MONTH. TEMPERATURES IN THE 90S WILL BE WIDESPREAD ON MONDAY...BUT THE GREATER CLOUD COVER SHOULD DAMPEN SOME OF THE HEAT ON TUESDAY. THIS CUTOFF LOW AND THIS MOISTURE POOL ARE FEATURES THAT ARE VERY SUBTLE AND MODELS HAVE A HARD TIME COMING TO A CONSENSUS ON THE DETAILS. RIGHT NOW IT LOOKS LIKE SHOWERS AND THUNDERSTORMS WILL INCREASE FROM THE SOUTH ON MONDAY...A FULL COMPLIMENT OF PRECIPITATION OVER THE ENTIRE REGION ON TUESDAY...AND MOISTURE MOVING OUT TO THE NORTHEAST ON WEDNESDAY FOR PRECIP OVER MOUNTAINS AND DESERTS. THIS SCENARIO WILL CERTAINLY BE MODIFIED QUITE A BIT OVER THE NEXT SEVERAL DAYS. L: 63 Quote Link to comment Share on other sites More sharing options...

Mattywx101 Posted September 18, 2015 Report Share Posted September 18, 2015 We had one day of below average temperatures this week. That makes 7 days with below average temps since June 20( 3 of those this month). This summer will very likely be the warmest summer on record on the coast here. Looking at the forecast from NWS L.A this afternoon, its pretty much a given this summer will go down as being the warmest summer on record here. I'll write out some summer temperatures near me in SLO county after the 21st. For now: Wednesday: H 66, L 48Thursday: H 81, L 59Friday: currently at 4:23pm, 87 and still rising.... Average 70/52.

Guest happ Posted September 19, 2015 Report Share Posted September 19, 2015 A quick glance at the records indicates that Mattywx101 is correct with regard to this being the warmest summer on record for some locations in San Luis Obispo and Santa Barbara counties. Warmest June, July, and August in Morro Bay. Warmest July and August in Santa Maria and Lompoc. Warmest August in Santa Barbara. No records set at San Luis Obispo or Pismo Beach, or at any locations more inland that I could find at first glance. The very high SSTs all across the Eastern Pacific would seem to have been more of a factor than excessive upper level ridging, but that's just my uneducated guess. Thanks for the data. I think Mattywx101 lives in San Simeon [near Morro Bay]. The warm ocean temps elevated minimums and even maximums at the coastline this summer. 1990 & 1994 were very warm summers. July 2006 was extremely hot across California. Looks like hot temps tomorrow and moisture on Sunday. Quote Link to comment Share on other sites More sharing options...

Guest happ Posted September 21, 2015 Report Share Posted September 21, 2015 I noticed the strong SSE winds this morning and what appeared to be a little stratus looking south toward Long Beach. There is an eddy circulation that could really help lower temps today. Clouds from the system off Baja are also moving north but rain chances may be meager. It is more humid today.

Guest happ Posted September 22, 2015 Report Share Posted September 22, 2015 Temps were off to a fast start this morning - I had a high of 91 at only 8:47 a.m. Then the SE breeze kicked up due to the eddy and it cooled things right off. 80 now at noon. Looking less and less likely that any rain will find its way here. It was a great reprieve from "mother nature" that I was surprised that it surprised NWS_LA that as late as 11:40AM still underestimated the strong eddy circulation. Several of the heat waves this summer have been altered by low pressure offshore. Its amazing what clouds and dew point temps can do to suppress heat. 87 / 75 Revised minimum: 71 Quote Link to comment Share on other sites More sharing options...

Mattywx101 Posted September 23, 2015 Report Share Posted September 23, 2015 Its official, warmest summer on record in San Luis Obispo since 1893 when records were first kept. For San Luis Obispo this summer temp came out to 70.5, average is 66.3. The previous record was last summer 2014, at 68.1. Many other coastal spots also had a record warm summer here. Hopefully will see some numbers soon. Anyway, nice cooling trend has commenced, yesterday: 84/68, today: 70/60. Sea temp off Cape San Martin was 68 the other day, now down to 66. Average sea temp at this time of year is in the 58-60 range off SLO. Quote Link to comment Share on other sites More sharing options...
